IMPROVEMENT IN BUCKLES.

The Schedule referred to in these Letters Patent and making parl: of the same.

To all whom 'it 'may concern Be it known that I, JOHN F. MARTIN, of Harrisburg, in the county of Linn and State of Oregon, have invented a new and improved Buckle; and I do hereby declare `that the following is a full, clear, and eX- act description thereof, which will enable others skilled in the art to make and use the saine, reference being had to the accompanying drawing forming part of this specification, in which- Figure 1re "-resents a plan or top viewof my impl'oved buckle or harness-tastening.

Figure 2 is a longitudinal vsection of the same.

Figure 3 is a side view of the saine.

Figure tis a detail longitudinal section of part of the same. Y

Similar letters of reference indicate corresponding parts.I

rlhis invention relates to a new device for connecting and locking together harness-straps and traces,`

in place of the buckles generally employed.

The invention consists in the use of two corrugated plates, which, when forced together, will bend and clamp one of the straps between them, the endof' D is'another metal plate similar to O. e., with one transverely-corrugated surface.

The strap B, being drawn through the loops a b, rests upon the corrugated surface ofthe plate C. The plate D is then placed upon the strap B above the plate O, so that B will be in contact with the corru- .gated surfaces of both.

A screw, E, is next fitted through the plate D, and strap B into the plate O, and, as it is being turned, it forces the plates together so asto more or less bend the leather into their grooved surfaces, as indicated in g. 4. The strap B is thus very securely held between the plates O D, not so muohfby the screwE as by the ribs on the said plates.

In order. to lock the plates together to prevent a disturbance of their relative positions, I prefer to prof vide projecting ears, l e, on the edges of the saine, the ears having overlapping shoulders, as shown in fig. 3, wherebythe separate longitudinal motion of the plates is entirely prevented-a -The screw may, however, answer the same purpose without the use of the said ears.

The strap B has a number of apertures, of which one receives the screw.

Having thus described my invention,

I claim as 4new and desire to secure by Letters Iatent- The plates C D, each apertured at one end, trans-A
